That's an internal PCM problem, likely a bad PCM. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

If you clear the code, does it come right back? Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
